ARTHUR W. BURT, OF ROSELLE PARK, NEW JERSEY.

DOSE-STOPPER.

Specification of Letters Patent.

Patented. June 9, 1908.

Application filed October 1, 1906. Serial No. 336,838.

To all whom it may concern:

Be it known that I, ARTHUR W. BURT, a citizen of the United States of America, residing at Roselle Park, in the county of Union and State of New Jersey, have invented certain new and useful Improve- .ments in Dose-Stoppers, of which the following is a specification.

My invention relates to bottle stoppers, and particularly to those known as dose stoppers, and. it consists primarily in an arrangement of devices, which enables me to measure a dose and then remove it, and no more, from the bottle without removing the stopper from the bottle, also preferably in so constructing, arranging and combining the devices that they are applicable to bottles of ordinary form, and do not require that the bottle shall be altered to accommodate it for use with the said stopper.

Figure 1, exhibits a bottle containing such a stopper, with. the parts in the positions they ordinarily occupy when the bottle is closed. It is represented. as being about half lilled with a liquid. Fig. 2, is a central, vertical, sectional view of such a bottle and stopper, but the relative positions of the parts are changed, the stopper being shown in the position it usually occupies when medicine or other liquid is, or is about to be drawn into the dose measuring part of the stopper. Fig. 3, is an upper face plan. view of thecork part of the stopper. Fig. 4, is a central, ver tical, sectional view of a portion of a bottle and a part of a modified stopper. Fig. 5, is a central, vertical, sectional view of a bottle equipped with a still further modified dose stopper, embodying the elements of my in vention, but not quite so economical to manufacture, as that shown in Figs. 1 and 2. Fig. 6, is a central, vertical, sectional view of a bottle equipped with a dose stopper, which embodies the principal features of the devices of Figs. 1, 2 and 5.

B, is the bottle which may and usually is of common form.

6, is the cork arranged to lit closely in the neck 7 of bottle B, but when I use the word cork herein, 1 do not intend to refer only to the material known as cork, but to all materials suitable for closing the mouth of a bottle. This cork 6, is apertured preferably at the center, to permit the passing through it of a glass tube 8, which is preferably of quite small diameter at the upper part, but enlarged at the lower part and graded to hold a given amount of liquid, say a teaspoonful, between its lower end and its neck 9. At the lower end it is preferably constricted to form a small aperture 10.

The cork 6, has a channel groove or passage 11, extending through it, preferably opening at the side into the aperture 12, in the cork. This location of the groove 11, permits it to be more readily cut or otherwise formed, than would be the case were it independent of aperture 12, but their conjunction is not absolutely necessary.

Upon the outer part of the neck 9, of tube 8, I construct a lug or stop 14, of such size, shape and location that when the tube is drawn out until this stop bears against the lower face of the cork 6, it will, if properly adjusted, close the vent aperture 11. A second cork 15, may be supplied for closing the mouth of the tube 8.

The operation is as follows: The bottle B, may be filled or emptied as is any other bottle, but if it is desired to use the contents in divided portions, and to pour out one of the portions at a time, then my stopper may be conveniently brought into use. With the stop 14, covering vent groove 11, and the cork 15, in place, it may be inserted in the neck of bottle B, as any other cork would be and it will elit'eotually close that bottle and prevent the exit of its contents by pouring or evaporation. But if a dose be required, the stopper need not be removed to obtain it. The tube 8, is depressed or turned, either at pleasure, until stop 14, clears vent 11,. and the cork 15, (if one is used) is removed. The measuring part of tube 8, is lilled, (if not already thus) or half filled if a half portion is desired, either by applying suction at its open end or by tilting the bottle until that is accomplished. Then the bottom of the bottle is tilted upward and the liquid will flow away from aperture 10, so that no more, for the time, can enter there. Having thus measured the dose, the user pours it out, into the patients mouth or a spoon or other receptacle, assured that no more than has been measured off, will be given and also that the liability of spilling the dose is almost if not altogether eliminated. Not only so, but the liability of dropping some of the liquid from the surface of the stopper, ever present with those forms of stoppers which need to be removed from the bottle to be discharged, is also eliminated. This feature renders it particularly effective as a laboratory tool, for measuring liquids that are corrosive in their action; and it is economical as well, in that the quantity which each time coats a spoon or common measuring glass and must thereafter be washed oil and thereby lost, is hereby saved. Its convenience is moreover noticeable in that other appurtenances are unnecessary.

derstood from that already given. In it, however, the tube is marked 28, and the lower aperture 30.

What I claim as my invention and desire to secure by Letters Patent is:

1. A dose stopper composed of a cork adapted to fit in the neck of a bottle, and a measuring tube extending through said cork,

The bottle of medicine or other chemicai nnd provided with apertures, one adapted to stands ready for use at all times. N o spoon 1 need be sought, no glass of water to hold the spoon after administering the dose. Indeed the patient, if need be, may carrythe fully equipped bottle in his pocket, always ready for service and yet not cumbersome or inconvenient to carry.

That it does not require a special bottle is of so readily recognized importance as to hardly need mention.

, Fig. 4, shows a modification. The tube 8, and bottle 7, are as before except that the stop 14, is omitted. The cork 16, is, however, varied. Instead of an internal vent groove 11, extending through the cork, this cork has a short vent groove 21, on its outer face, extending up to a level just below the up er .part of the contact joint between the cor r. and the neck of the bottle when the cork is tightly inserted.

ready" described. When liquid is to be The operation is very similar to that almeasured and drawn from the bottle, the cork 16, is so loosened or raised in the neck of the bottle, that exterior air can enter the bottle through groove 21, the upper end of which is then preferably above the contact joint aforesaid, though the cork is still in the bottle.

Still another form of venting device is shown in Fig. 5. In this form the measuring tube 18, is given a bend to permit aperture 20, at its lower end to lie as near the side of the bottle as possible, as that facilitates its filling and other manipulation, though it is manifest that a straight tube extending in a slanting direction through the cork, would accomplish substantially the same result. At the neck it carries a by-pass 31, with apertures 17 and 19, which by-pass, though connected with and lying within the tube, is also in the cork and as much independent, so far as giving vent is concerned, as is either of the other vent passages described.

When it is desired that the bottle shall be closed the tube is drawn out until aperture 17, is within the cork, and it will be closed thereby, but when, the liquid is to be drawn, the relative positions of the cork 26, and the tube 18, are so changed that aperture 17 is below the bottom of the cork and aperture 19, above the top. The vent will then be open and the measuring and drawing may proceed.

An extended description of Fig. 6 is unnecessary, inasmuch as it will readily be unoperate as an inlet, located in that part of the tube intended to lie below the cork and within the bottle, and the other adapted to operate as an outlet, located in that part of the tube intended to lie above the cork and without-the bottle, said stopper being provided. with a vent passage independent of the main passage through the measuring tube, both the vent and the outer tube aperture being adapted to be readily closed, all combined substantially as set forth.

2. A dose stopper, composed of a cork adapted to fit in the neck of a bottle, a measuring tube extending through said cork and provided with a small inlet at one end and a mouth at the other end, said stopper being provided with a vent passage independent of the main passage through the measuring tube, and means for closing said independent ventpassage, all combined substantially as set forth.

3. A dose stopper, composed of a cork adapted to fit in the neck of a bottle, a measuring tube extending through said cork, and having a body which is enlarged below said cork, and provided with a neck which is smaller in diameter than the body, also a small inlet at one end and a mouth at the other end, said stopper being provided with a vent passage independent of the main passage through the measuring tube, and means for closing said independent vent passage, all substantially as set forth..

4. A dose stopper, composed of a cork adapted to fit in the neck of a bottle, a measuring tube extending through said cork and to a point near the side of the bottle and provided with a small inlet at the point near the side of the bottle and a mouth at the other end, said stopper being provided with a vent passage independent of the main passage through the measuring tube, and means for closing said independent vent passage, all combined substantially as set forth.

5. A dose stopper, composed of a cork adapted to fit in the neck of a bottle, a measuring tube extending through said cork and provided with a small inlet at one end and a mouth at the other end, and a body constructed to hold a predetermined quantity of liquid, said stopper being provided with a vent passage independent of the main passage through the measuring tube, and means for closing said independent vent passage, all combined substantially as set forth.
